Nuther Mustang II front end Q

Hey all,

I'm gonna be putting a mustang II front end into a 64 MG Midget project I've got and I got a couple questions about it.

First, I know the lower control arm should be level with the ground for it to work best, but I need to know what angle to put the upper control arm at, also, should there be any castor built into it (like the upper ball joint forward or behind the lower)?

I've seen lots of kits for these, but I'm a little unsure about what they mean by some of the measurements like tread width, I don't think they are talking about the tire tread since they have no idea what wheel the user is gonna have. It would be nice if they had a dimension for wheel mounting surface to wheel mounting surface, that would be a lot more useful to me. The frame width doesn't matter to me since I will be building the frame around the front suspension.

It probably won't matter though, since a midget is so small I doubt anyone makes one narrow enough. I've pretty much resigned myself to making it all custom.

Welcome to

Tread width is the distance from wheel mounting flange to wheel mounting flange. It is 56 inches on most kits ... way too wide for your project IMHO ...

Thanks Deuce,

I agree with you.

I think the stock width is around 48 inches, I measured it on my 73 once, but can't remember the exact number.

I plan on making the front end a bit wider than stock though, so if I pick up a do it yourself kit, I should be able to modify the cross member to fit.

I live out in the country in central California, so about 98 percent of my driving is on long country roads, I am just wondering how much caster I should build into it so it cruises comfortably at freeway speeds. Midgets were designed for narrow twisty little roads in the English countryside, so they can get a bit freaky at around 80 on the freeway.

Fat Man makes a 2" narrowed M II kit.
56 1/2" is their stock width.
